Week 0: Participants are informed about the study and trained in the use of the mobile application. The mobile app is installed on their smartphones. Educational animation videos and modules are watched with the researcher in a predefined order. Questions about animations are answered. Videos are downloaded to the participant's phone. DFU photographs are recorded. Weeks 1-12: Participants are instructed to use the app regularly between weeks 5-12. Video watching days and durations are logged using a tracking form. Weekly push notifications remind participants to use the app. Weekly phone calls are made to assess engagement using a structured checklist. DFU photographs are taken at weeks 8 and 12. At week 12, data are collected in person, including: DFU size (length × width) with disposable paper ruler Metabolic parameters from blood tests Wagner-Meggitt classification Re-ulceration assessment

Participants provide consent and receive baseline information. DFU photographs are taken at baseline, week 8, and week 12. At week 12, the same outcome measures as the intervention group are collected. After the study ends, participants are provided with access to the mobile application.
